摘要
通过磺化腐植酸对重金属Ni(Ⅱ)吸附性能的实验,研究了吸附过程中的吸附等温线,探讨了吸附热力学特征和吸附动力学模型.结果表明:在室温条件下(20~25℃),pH为5~6,吸附平衡时间120 min,磺化腐植酸对Ni(Ⅱ)吸附类型符合Freundlich吸附模型,吸附过程可用Ho准二级反应动力学模型描述.
Through the Sulfonated humic acid composite adsorbent for heavy metal Ni (I1) experiment, Studied of the adsorption isotherm, discussed of the adsorption thermodynamics characteristics and the adsorption dynamics model. Results show that at room temperature (20-25 ℃), pH is 5-6, the adsorption equilibrium time is 120 min, In line with the Freundlich adsorption model, Sulfonated humic acid for Ni (I1) adsorption process of available Ho, the secondary reaction kinetics model description.
